RBR50 LAN Port Issues
I have an iMac running on High Sierra 10.13.6 that was working fine on my previous set up.
Today, I had Spectrum upgrade my cable modem to a GIG modem.
Wireless works flawlessly. Flies! ...
I think your ISP modem already has a built in router.
Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, LAN to LAN and configure AP mode on the Orbi router.
I called Spectrum and they said the cable modem is only a modem, not a router.
They also said that since I can plug in directly to the cable modem with the iMac and get internet access, they can't help trouble shoot the issues withi the ORBI.
Now what?
